iPhone locking during calls

[mvpapa]

Huh? Since the latest iOS "upgrade" my phone autolocks itself *during* calls. I have to swipe and unlock to even hang up the call.
Any thoughts on what happened here and how to fix it?

It's a glitch I had it till I restored my iphone

I know this is a necro-bump but I used to have this problem on my 4S and still have it on my 6. No amount of restoring from backup or as new has solved this.

I googled this bug and found old discussions on Apple's board but no solution was put forth.

Anyone else have this problem?
